Has anyone else experienced the issue with this new [proton] interface whereby every now-and-then, any interaction (e.g. mouse click) that should bring up a menu or dialog simply does not work -- except for the tab bar? I even have to kill the browser via task manager, because I can't get the menu for the exit command.

I did CTRL+SHFT+K to bring up the console and see if there is any debug info in there, but nothing is generated. Either the console is also broken for browser chrome or So, even if I created a bug report, the dev's will just stick their heads in the ground and shrug.
